Chair capable of being adjusted as a chaise

ABSTRACT

A chair capable of being adjusted as a chaise comprises a cushion assembly including a first cushion, a second cushion and a third cushion; a first rotary shaft being used to pivotally connect the first cushion and the second cushion; a second rotary shaft being used to pivotally connect the second cushion and the third cushion; an adjusting unit installed below the first cushion; a chair support structure being installed between the first cushion, a second cushion and a third cushion; the chair support structure including an assisting support frame and a support frame; the assisting support frame installed between the first cushion and the third cushion; and the support frame being installed below the third cushion.

FIELD OF THE INVENTION

The present invention relates to chaises, and particularly to a chair capable of being adjusted as a chaise which has both the function of seating and lying so as to provide the inconvenience to users.

BACKGROUND OF THE INVENTION

U.S. Pat. No. 5,950,259 discloses a lounge chair that includes an upper body support portion, an aperture extending through said upper body support portion, and a movable flap secured to the upper body support portion for selectively covering and uncovering the aperture. In particular, the flap can be repositioned to cover and uncover an aperture through a upper body support portion without having to get up out of the chair and without having to reposition the upper body support portion.

U.S. Pat. No. 4,470,630 discloses a portable folding chair which is adaptable for use in an upright conventional sitting mode, in an inverted position as a back rest and in a collapsed position as a carrying device. The rear leg member and chair back are adjustable so that the rear leg member defines a comfortable headrest in the inverted backrest mode and a flap is provided which defines a lounging mat in the back rest mode which, in use, anchors the chair in place and in the collapsed carrying mode defines with the seat and back panels a covered carriage compartment.

While all of the aforementioned prior art constructions are more than adequate for the basic purpose and function for which they have been specifically designed, they are uniformly deficient with respect to their failure to provide a simple, efficient, and practical pivoted leg assembly that can support the main lounge support panels at a variety of different angular orientations relative to one another, as well as the horizontal plane. While all of the prior art devices include at least one horizontally disposed support panel that coincides with the user's mid torso, there are many instances wherein it would be desirable to dispose the seat portion of the lounge chair at an angle other than the horizontal plane. As a consequence of the foregoing situation, there has existed a longstanding need for a new and improved type of adjustable angle chaise lounge construction that employs a unique leg support arrangement that permits the three main lounge panels to be disposed at a variety of angles relative to one another, and the provision of such a construction is a stated objective of the present invention.

SUMMARY OF THE INVENTION

Accordingly, the primary object of the present invention is to provide a chair capable of being adjusted as a chaise which has both the function of seating and lying so as to provide the inconvenience to users.

To achieve above objects, the present invention provides a chair capable of being adjusted as a chaise which comprises a cushion assembly including a first cushion, a second cushion and a third cushion; a first rotary shaft being used to pivotally connect the first cushion and the second cushion; a second rotary shaft being used to pivotally connect the second cushion and the third cushion; an adjusting unit installed below the first cushion; a chair support structure being installed between the first cushion, a second cushion and a third cushion; the chair support structure including an assisting support frame and a support frame; the assisting support frame installed between the first cushion and the third cushion; the support frame being installed below the third cushion. The first cushion is used as a pad for seating; the second cushion is used as a chair back rested by the back of the user; the third cushion is folded with respect to the second cushion to be located at a backside of the second cushion.

The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE INVENTION

In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.

A chair capable of being adjusted as a chaise according to the present invention is illustrated in FIGS. 1 to 4. The present invention has the following structure.

A cushion assembly 10 includes a first cushion 11, a second cushion 12 and a third cushion 13. A first rotary shaft 14 is used to connect the first cushion 11 and the second cushion 12. A second rotary shaft 141 is used to connect the second cushion 12 and the third cushion 13. Thus the first cushion 11 is rotatable with respect to the second cushion 12 and the second cushion 12 is rotatable with respect to the third cushion 13.

A chair support structure 20 is installed between the first cushion 11, a second cushion 12 and a third cushion 13. In this embodiment, the chair support structure 20 has an adjusting unit 21.

The adjusting unit 21 comprises a lifting body 212 for lifting or descending the cushion assembly 10 of the chair, a press rod 121 for actuating the lifting body 212; and a base 213 with a plurality of wheels at a bottom of the base.

An assisting support frame 22 is installed between the first cushion 11 and the third cushion 13.

A support frame 23 is installed below the third cushion 13.

A positioning unit 111 is installed at a bottom side of the first cushion 11. The positioning unit 111 comprises a movable stud 1111 and a press button 1112 for releasing the stud 1111. A stopper 112 is installed at the bottom of the first cushion 11.

As the present invention is used as a chair for seating, the first cushion 11 is used as a pad for seating. The second cushion 12 is used as a chair back rested by the back of the user. The third cushion 13 is folded with respect to the second cushion 12 to be located at a backside of the second cushion 12. The support frame 23 is located below the first cushion 11 and confined by the studs 1111 of the positioning unit 111 by releasing the press button 1112 to move the two studs 1111 outwards, see FIG. 4.

Referring to FIGS. 5 to 9, the operation of making the present invention as a chaise. The press buttons 1112 are pressed and then the studs 1111 are moved inwards. The second cushion 12 is moved backwards slightly so that the support frames 23 are not confined by the two studs 1111. The third cushion 13 is unfolded from the second cushion 12 to a flat position. Furthermore the second cushion 12 is also moved downwards so that the cushion assembly 10 is wholly expanded as illustrated in FIG. 8.

Thus, when the chair is for seating, the chair can be located in the folded state. When the chair is as a chaise, the first cushion 11, second cushion 12 and third cushion 13 are expanded so that the user can lie upon the chaise.

The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
